What is sdn?

SDN stands for Software-Defined Networking, which is an approach to networking that allows network administrators to manage network services and applications using centralized, programmable methods. In SDN, network hardware is decoupled from the network control plane, and software is used to manage and configure the network. This approach offers greater flexibility, scalability, and automation than traditional networking methods. Some benefits of SDN include simplified network management, faster provisioning of network services, improved security, and reduced costs. SDN technology is used by various industries, including telecommunications, data centers, and cloud computing. Some popular SDN platforms include OpenFlow, Cisco ACI, and VMware NSX.
